Excerpt from an interview with Lee Diogeneia. Author, MSPI Editorial Director, vampire advocate, Lee never finds any downtime. But that’s okay. You can follow her on Facebook and Twitter.
It really depends on the type of editing and the editor. In general, proofing and copy editing is the same across fiction and creative non-fiction. However, the editor may not enjoy manuscripts outside of her interests. Developmental and Substantive editors, in my experience, tend to have strong preferences across types of creative non-fiction and fiction. Some even specialize in certain genres. I strongly believe that the editor you hire should both understand and enjoy your genre or type of novel. It’s a better working experience for both the writer and the editor.
